WILHELM BECKER, OF BREMEN, GERMANY.

ANCHOR.

Application filed March 26, 1921.

To all whom it may concern:

Be it known that I, WILHELM BECKER, a citizen of the German Republic, residing at Bremen, Germany, have invented certain new and useful Improvements in Anchors, of which the following is a specification.

The present invention relates to an anchor of the stockless type with pivoted shank, and consists in the provision of an anchor head having a wide base whose surfaces gradually converge at the ends of the head so as to form the arms and the flukes, the surfaces being either evenly curved or broken. Owing to this construction of the head, the latter will be guided so that, even if only one fluke should be in engagement with the ground and if the shank should, as a conse quence, set itself at an angle to the pull the anchor will not swerve or become detached.

A further feature of the invention consists in making the faces of the anchor concave so that while the flukes engage the ground, the surfaces at the base of the head remain on and more or less parallel with the ground. This will prevent the shank of the anchor from being forced into the ground and the flukes from being forced out of it by lever action. p

The end surfaces of the head, in converging onto the arms, approach the median axis of the anchor, a feature, which will add favourably to the steering of the latter.

In the accompanying drawings the invention is illustrated by way of example.

Fig. 1 is a perspective view of an anchor with curved end surfaces.

Fig. 2 is a plan of the anchor showing its position when only one fluke engages the ground, and

Fig. 3 is a cross-section on the line II of Fig. 2.

Fig. 4 is a perspective view of an anchor with nearly straight fluke arms.

Fig. 5 is an elevation of an anchor the flukes of which are formed entirely on the inner sides of the arms, and

Fig. 6 is an end View of the anchor head showing the concavity of the faces.

The cross head of the anchor has a wide base whence the faces a and the more or less curved even or broken end surfaces 6 and 0 gradually converge to form the arms and the fiukes. The shank e is pivoted at f to the cross-head in the usual manner. The

faces a. extend without interruption over the arms and the flukes and run to a point at the on two sides by boldly curved surfaces; the

arms 9 in Figs. 4% and 5 are nearly straight. The outer edges of the base overhang the flukes, i. e., the surfaces 6 and a in extending to form the arms, approach the median axis of the anchor. Thus the space between the fiuk s will be narrower than that between the bases of the arms, an arrangement which prevents objects from being jammed between the arms so as to impede the action of the anchor, since anything caught between and moving along the fluke edges, will be released when reaching the wider space between the base of the arms.

A particularly effective arrangement is shown in Fig. 5 according to which the flukes are formed entirely on the inner sides of the arms and extend close to the shank e.

In this case a considerable widening of the space from the flukes towards the base of the arms is produced, and the outer surfaces 6 and 0 can proceed in a uniform curve right to the tip of the flukes, a favourable steering effect being thus obtained.

I claim:

A stockless anchor including a shank and a far spreading rotatable cross head journalled to the shank and provided with broad supporting surfaces projecting laterally beyond the points of the flukes. of the anchor and having gradually ascending upwardly tapering end faces merging into the flukes and presenting smooth, unbroken end faces and having gradually ascending side faces, inclined inwardly and merging into the sides faces of the flukes to present continuous smooth side faces.

In'testimony whereof I aflix my signature in presence of two witnesses.
